Mini-ITX (often called ITX) cases are perfect for compact, high-performance PCs, but fitting a full-size GPU—think RTX 4090 models up to 350mm long and 3-4 slots thick—requires careful selection. In 2025, SFF trends favor better airflow, modular designs, and RTX 50-series compatibility. Whether you’re targeting “best mini-ITX cases for full-size GPUs,” “top ITX PC cases with GPU support,” or “compact ITX builds for large GPUs,” this guide covers it all.
